With the new NL series from Höcherl & Hackl TTMS did expand their range of four quadrant power supplies with an additional 50 units. The NL models are designed for practical use within laboratories as well as in the fields of production and quality assurance. Each linearly regulated Source-Sink is a voltage/current source as well as a current sink in a single device. The various types cover a voltage range of up to ±50V (bipolar) and up to 100V (unipolar), at currents of up to 320A. Power ratings ranging from 100W to 3.520W are available. If possible, we produce units with higher power ratings upon request.

The unipolar version of the Source-Sink features a restricted four-quadrant operating mode and allows a negative output voltage of up to -1V. This technical facility makes it possible to compensate voltage drops across the device’s supply lines. The required voltage/current values as well as the limit values can be entered and set via the digital user interface, the digital communication interfaces or the analog interface. The devices feature RS232, USB as well as a practical analog interface as standard.

Battery test software and software for making a dynamic sequence are available free of charge. The devices in the NL range stand out with their excellent dynamic characteristics and rapid quadrant switching. The units can be used as a four quadrant amplifier as well. With their robust mechanical housings, the devices are designed for industrial 19″ rack installation or for use as bench-top units.
Applications include testing of batteries and accumulators, testing electrical drive systems and testing solar cells and panels.

WHAT OUR CUSTOMERS SAY

ABB

"The ABB Power Grids Jumet organisation is an innovative development and production facility of ABB that manufactures active filters and battery energy storage systems to support a stable grid. To test these systems we have acquired two Cinergia GE/EL +120kVA eplus units capable of doing grid emulation (AC + DC), operating as an electronic load (AC +DC) and being a battery emulator. We have experienced very good support from TTMS in obtaining these two Cinergia units. This included organising an on-site demonstration and supplying loan systems prior to the delivery of our final systems. This way we could start testing as early as possible. TTMS also organised training for the operators from the original manufacturer. This support allowed us to introduce the first battery energy storage systems even prior to the full delivery of the Cinergia systems."

Sasan Rafii-Tabrizi

University of Luxembourg

“At the Energy and Environment department of the Faculty of Science, Technology and Medicine (FSTM) of the University of Luxembourg we do have different research projects related to green energy contributing to the development of eco-cities. As a long-standing partner of our research unit, TT&MS has proven that they are able to answer even the most complex questions in a professional manner. They have shown that they are always up to date with the latest technology and do not spare any effort to look at the application and even the situation on site. The exchange of ideas was always very pleasant and took place quickly. We look forward to further years of fruitful cooperation.”
